ANDREW wnsrLAxn, or LEADvILLE, COLORADO.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 292,454, dated January 22,\1884, l Application filed July3, 1882. (No model.)

To all whom it may concern:A

Be it known that I, ANDREW VEsTLAKE, a citizen of the 'United States of America, residing at Leadville, inthe county of Lake and State of Colorado, have invented certain new and useful Improvements in Car-Trucks, of

which the following is a specification, refer# ence being had therein to the accompanying drawings.

My invention relates to a new construction of short car-trucks having independent axles; and it consists in atruck-frame having a double line of arch-bars on each side of the truck, rigidly connected by means of channel-plates andbolts, and in other improvements, all of which will be fully understood by the following description and claims. Y

.In the accompanying drawings, Figure lis a side view of my improved car-truck. Fig. 2 is a top view ofthe same. Fig. 3 is an end view. Fig. 4 is a bottom view. Figs. 5, 6, land 7 are detached and enlarged views.

My truck-frame is made with a double line of arch-bars on each side of the truck, one.

line being placed each side .of each wheel and each line having three arch-bars, or two archbars and a tie-bar, as shown at AB C, Fig. 1. These lines of arch-bars are connected by two channel-plates, D, and bolts E, as shown in Figs. 1- and 2. They are also stiffened by means of the oil-boxes F, having flanges f on' their insideends, which are riveted or bolted together in the middle of the truck, thus stift ening the truck and serving the purpose of a continuous axle to keep the wheels in gage. The outside ends of these oil-boxes are fastened to the inside line of arch-bars by pedestal-bolts Q. A series of diagonal braces, H, on the under side of `the truck, are bolted to the arch-bars. These braces extend from the inner line of arch-bars on one side of the truck to the inner and outer line of arch-bars on the other side of the truck, and are bolted to the same. A set of short cross-braces, M, con* nect the two inner lines of arch-bars and assist in stiffening the truck-frame. Between the wheels are two long oil-boxes, F,'having openings at the side instead of the'end, said openings being provided with covers, Fig. 3, thus affording convenient access tothe in terior ofthe oil-chambers for the insertion of brasses of the inside journals, and also for packing and oiling the same. The outer oilboxes, N, are of the usual form. rIhe back ends of the inner and outer oil-boxes are chilled to prevent wearing away by the hub of the wheel, and thereby prevent` the endthrust of the axles. A chilled washer, K, made open at its lower end, so as to be sprung ,over the axle betweenthe hub of the wheel L and the oil-box F, as seen in Figs. A5 and 6, for the purpose of preventing end-thrust of the axle as the hub of the wheel and the back end ofthe oil-boxes become worn. This chilled washer varies in thickness as the space to be filled may require.

Between the two ehannelfplatesD is aswing- 4ing bolster, N, having a suitable end-play, and

supported by elliptic springs O, resting upon the sand-board P, Fig. 4.

Coiled or rubber springs may be used, if desired.

Having described my invention ,what I claim l. In a car-truck, the combination, with a double line of arch-bars, A, on each side of the truck, of connecting arch and tie bars B C, transverse connecting channel-bars D, and* the diagonal long and short braces H and M, arranged substantially as herein shown and described.

2. In a car-truck, a series'of independent axles, in combination with the oil-boxes having chilled ends, and chilled washersnK, substantially as and for'the purpose herein shown and described. v

3. In a car-truck, the long oil-boxes F F,
